Description

Technisches GebietTechnical area

Die Erfindung betrifft ein Filterelement bestehend aus einem zick-zack-förmig gefalteten Filtermedium.The The invention relates to a filter element consisting of a zig-zag folded filter medium.

Stand der TechnikState of the art

Aus dem Stand der Technik sind Rundfilterelement aus einem zick-zack-förmig gefalteten Filterpapier oder Filtervlies bekannt. Diese Rundfilterelemente sind an ihren Stirnseiten mit Endscheiben versehen. Ein Rundfilterelement wird zunächst aus einer Filtermaterialbahn hergestellt und zwar durch zick-zack-förmiges Falten der Materialbahn. Diese wird in eine konzentrische Form gebracht und Endscheiben an die Stirnseiten dieses Filtermediums angeklebt oder angeschweißt. Bei dem Verfahren muss darauf geachtet werden, dass der Faltenabstand gleichmäßig ist und jede Falte von der benachbarten Falte einen gewissen Abstand aufweist damit eine gleichmäßige Filterbeladung erfolgen kann.Out The prior art circular filter element from a zigzag-shaped folded filter paper or filter fleece known. These round filter elements are at their End faces provided with end plates. A round filter element is first made of a filter material web by zig-zag folding the material web. This is brought into a concentric shape and end plates adhered to the end faces of this filter medium or welded. In the procedure, care must be taken that the pleat spacing is uniform and each fold from the adjacent fold a certain distance thus has a uniform filter loading can be done.

Aus der JP 11-285609 A ist ein Filterelement bekannt, das aus einem zick-zack-förmig gefalteten Filtermedium besteht, welches längs der Faltentaschen mit abdichtenden Seitenstreifen versehen ist, wobei das Filterelement zu einem Rundfilterelement geformt ist, derart, dass sich die Endfalten gegenüberstehen und miteinander verbunden sind.From the JP 11-285609 A For example, a filter element is known which consists of a zig-zag folded filter medium which is provided along the folding pockets with sealing side strips, wherein the filter element is formed into a round filter element, such that the end folds face each other and are interconnected.

Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen näher erläutert.The The invention will be explained in more detail with reference to embodiments.

Kurze Beschreibung der ZeichnungenBrief description of the drawings

Es zeigt 1: Ein Filterelement mit SeitenstreifenIt shows 1 : A filter element with side strips

2: Das in 1 dargestellte Filterelement in konzentrischer Form. 2 : This in 1 illustrated filter element in concentric form.

Ausführungsform(en) der ErfindungEmbodiment (s) the invention

Das in 1 dargestellte Filterelement besteht aus einem Filtermedium, welches zick-zack-förmig gefaltet ist und an den beiden quer zu den Falten verlaufenden Stirnseiten mit einem Vliesmaterial versehen ist.This in 1 filter element shown consists of a filter medium, which is folded zig-zag and is provided at the two transverse to the folds end faces with a nonwoven material.

Dieses Vliesmaterial ist beispielsweise an dem Filtermedium angeklebt.This Nonwoven material is, for example, adhered to the filter medium.

Durch diese Anordnung werden Filtertaschen gebildet. Die Filtermaterialbahn wird in einem nächsten Prozessschritt zu einem konzentrischen Filterelement geformt (2). Dabei überlappen sich die überstehenden Seitenstreifen an der oberen Stirnseite und an der hier nicht dargestellten unteren Stirnseite. Diese Seitenstreifen können miteinander verklebt werden. Gleichzeitig werden die beiden sich gegenüberstehenden Endfalten ebenfalls mit einander verbunden, so dass ein zuverlässig abgedichtetes Rundfilterelement entsteht.By this arrangement, filter bags are formed. The filter material web is formed in a next process step to a concentric filter element ( 2 ). In this case, the overlapping side strips overlap on the upper end side and on the lower end side, not shown here. These side strips can be glued together. At the same time the two opposing end folds are also connected to each other, so that a reliably sealed round filter element is formed.
